ep ilieatien filed January This invention relates to apparatus used inthe recovery; of-precious metals and for its b ect the provision of a-novel machine by means of Whichfine particles of.

' gold or other preciousmetals be recovered from sand; crushed or'eand the like, the "construct on and arrangement being such that even particlesof suchj finenessjthat'they I with those of a heavier nature will float upon Water will be recoyeredgalong s tha f o hi ing of yaluewill'belost. v y

treatment to remove precious metal there from.

From the foregoing description and'a study of the drawings it Will be apparent that I have thus provided a simply constructed and j rapidly operable mechanism whereby particles, no matter how small, of 7 -gold or other similar metals may be reclaimed.

The device is adapted to operate continuously'as the supply of material thereto may be made continuous. I It is believed that the construction, operation and advantages Will be readily apparent to one skilled in' the art Without further explanation.

l1ile'I have shown and described a preferred embodiment should be understood that I reserve the right to make such changes in the form, construction and arrangementof parts as WVlll not depart fromthe spirlt of the invention'or th'e'scop'e of the subjoined claims.
